"Ensuring that I and my office have the community's trust and confidence is paramount to me, which is why I invited an independent review of this matter," Foxx said in a statement. "I welcome this investigation and pledge my full cooperation and the cooperation of my office."

A grand jury indicted the actor on 16 counts in early March. Foxx's office dropped the charges about three weeks later, giving no detailed explanation for why the case was abandoned. Smollett has maintained his innocence and insisted he was attacked.

The Chicago Tribune first reported Foxx's request Friday and reported Cook County Independent Inspector General Patrick Blanchard set a letter to Cook County Board President Toni Preckwinkle and other county leaders informing them of Foxx's request.

Blanchard wrote that Foxx asked for a review "of the circumstances surrounding the resolution of criminal charges formerly pending against Jussie Smollett." He wrote that his office would proceed with the review.

The city of Chicago filed a civil lawsuit Thursday in Cook County court against Smollett, who is black and gay, in a bid to recoup the costs of investigating his claim that masked men beat him Jan. 29 in Chicago, shouted slurs and wrapped a rope around his neck.

The suit comes after Smollett refused the city's demand that he repay it $130,106. A spokeswoman for Smollett's legal team said they had no comment on the lawsuit or Foxx's request for the inspector general review.
